If you’ve felt a sharp, burning or electric pain travelling from your lower back through your buttock and down your leg, you know how much it can disrupt your day. Sitting through a work meeting, driving along Great North Road or getting out of bed can all become a challenge. Many people in the Inner West start by searching for a chiropractor for sciatica in Five Dock, but the first question is usually simpler: why is this happening to me?
This guide explains what sciatica is, the seven most common causes of lower back and leg pain, and when it’s time to get it assessed.
What Is Sciatica?
Sciatica is pain that follows the path of the sciatic nerve. This is the longest nerve in the body. It starts in the lower back, runs through the buttock and travels down the back of each leg. Sciatica is a symptom, not a diagnosis. Something is irritating or compressing the nerve, and finding out what that is matters most.
Typical symptoms include:
- Pain in the lower back, buttock or leg, usually on one side.
- Tingling, “pins and needles” or numbness in the leg or foot.
- Weakness in the leg.
- Pain that worsens when sitting, coughing or bending forward.
1. Lumbar Disc Bulge or Herniation
This is one of the most common causes of sciatica. The discs between your spinal bones act as cushions. If a disc bulges or its soft centre pushes outward, it can press on a nearby nerve root. This often causes sharp leg pain, sometimes worse than the back pain itself. Disc problems can develop gradually from repeated bending and lifting, or flare up suddenly after a simple movement like picking something up off the floor.
2. Tight or Irritated Piriformis Muscle
The piriformis is a small muscle deep in the buttock, and the sciatic nerve runs close to it, and in some people through it. When the muscle becomes tight or inflamed, it can irritate the nerve and mimic true sciatica. This is often called piriformis syndrome. It’s common in people who sit for long hours or run regularly, and it’s one reason a thorough assessment matters. Not all leg pain that feels like sciatica starts in the spine.
3. Lumbar Joint Dysfunction and Restricted Movement
The small joints of the lower back are designed to move smoothly. When they become stiff, locked or irritated, surrounding muscles tighten in response. This can change how you move and put extra pressure on the nerves leaving the spine. Joint restriction often shows up as a stiff, achy lower back, with referred pain into the buttock or thigh. Hands-on care such as gentle chiropractic adjustments is commonly used to help restore normal joint movement.
4. Spinal Stenosis (Narrowing of the Spinal Canal)
Spinal stenosis happens when the space around the nerves in your lower spine narrows. It’s more common as we get older because of age-related changes in the discs and joints. People with stenosis often notice leg pain, heaviness or cramping when standing or walking for longer periods, which eases when they sit or lean forward. If this sounds familiar, it’s worth having it properly assessed rather than putting it down to “just getting older.”
5. Poor Posture and Prolonged Sitting
Modern life is full of sitting. Long commutes into the CBD, desk jobs and evenings on the couch all place sustained load on the lower back. Over time, this can weaken the deep stabilising muscles, tighten the hips and overload the discs and joints. Many people who come in with sciatica-type pain don’t remember a specific injury. Their pain built up slowly from everyday habits. Improving movement patterns and posture is a big part of lasting recovery, which is why correcting how you move matters as much as relieving the pain.
6. Muscle Strain and Core Instability
A strained muscle in the lower back or hip can refer pain into the leg and mimic nerve pain. Weakness in the core and gluteal muscles can also leave the spine under-supported. The result is that everyday tasks like gardening, lifting groceries or playing weekend sport place too much stress on the lower back. When the supporting muscles aren’t doing their job, the nerves and joints can become irritated more easily.
7. Sacroiliac (SI) Joint Irritation
The sacroiliac joints connect the base of your spine to your pelvis. When one becomes irritated or moves poorly, pain can spread into the buttock, hip and back of the thigh, which often feels very similar to sciatica. SI joint problems can follow pregnancy, a fall, a sporting injury or long-term asymmetry in how you stand and walk. Because the symptoms overlap with other causes, a hands-on examination helps tell them apart.
How Can a Chiropractor Help With Sciatica?
A good assessment looks beyond where it hurts. A chiropractor will usually ask about your history, examine your spine, hips and nerve function, and test how you move. The aim is to find the root cause of the nerve irritation, not just the symptom.
Depending on what’s found, care may include:
- Gentle spinal and joint adjustments to improve movement.
- Hands-on soft tissue work or massage to ease muscle tension.
- Functional movement and rehabilitation exercises to build stability and strength.
- Practical advice on posture, sitting, lifting and staying active.
The goal is to ease your pain and give you the tools to stop it returning. Quick relief is helpful, but long-term movement control is what keeps sciatica from coming back.
What You Can Do at Home
While you’re arranging an assessment, a few simple steps can help:
- Keep moving gently. Short, regular walks are generally better than bed rest.
- Break up sitting. Stand, stretch or walk every 30 minutes.
- Avoid heavy lifting and deep forward bends while symptoms are flared up.
- Use heat on tight muscles if it feels soothing.
- Sleep in a supported position, such as on your side with a pillow between your knees.
When Should You Seek Help for Sciatica?
Many cases settle with the right care, but don’t wait if your symptoms are severe or not improving. It’s worth getting assessed if:
- Pain has lasted more than a few days or keeps returning.
- Your leg feels weak, numb or tingly.
- Pain disrupts your sleep or work.
- Sitting, standing or walking has become difficult.
Seek urgent medical attention (emergency department or call 000) if you develop loss of bladder or bowel control, numbness around the groin or inner thighs, or rapidly worsening leg weakness. These can be signs of a serious condition that needs immediate care.
Frequently Asked Questions
Can sciatica go away on its own?
Mild cases often improve within weeks, but recurring or severe pain usually has an underlying cause that benefits from proper assessment.
Is chiropractic care safe for sciatica?
When delivered by a qualified, registered practitioner after a thorough assessment, chiropractic care is considered a safe, conservative option for many people with lower back and leg pain.
Should I rest if I have sciatica?
Short periods of rest are fine, but staying gently active generally supports recovery better than prolonged rest.
